Thanks Andrea !!
Yes, I could store the value on the Panel which holds the form - but then I
couldn't use it as stateless. Or in WebSession, but it's not adequate...
Also. I could use a String and make the conversion hardcoded..
But I searched the converters, and I tried this (maybe a little complicated)
and it worked allright !
public class MyWebApplication extends WebApplication {
@Override
protected IConverterLocator newConverterLocator() {
ConverterLocator locator = (ConverterLocator)
super.newConverterLocator();
locator.set(MyEnum.class, new MyEnumConverter());
return locator;
}
}
public class MyEnumConverter implements IConverter<MyEnum> {
@Override
public MyEnumconvertToObject(String s, Locale locale) {
try {
return MyEnum.valueOf(s);
} catch (Exception e) {
log_error("MyEnum.valueOf(s) " + s, e);
return null;
}
}
@Override
public String convertToString(MyEnum myEnum, Locale locale) {
return myEnum.name();
}
}

Asunto: Re: Error with Hidden Field and its enum value
The error occurs because Wicket convert your enum to a string when the
form is rendered, then it tries to do the opposite converting the string
to your enum. And here we have the problem. Wicket doesn't fin a valid
converter (see JAvaDoc of FormComponent.convertInput) to obtain your
enum from its string value. But the real question is: do you really need
to have such hidden field in your form? Why can't you simply get rid of it?
